` WINDOW-PULLEY.

Application filed January 7, 1916. Serial No. 70,836. v

To aZZ whom it may concm:

Be it known that I, EDWARD B. YOUNG, a

'citizen of the United States, residing at Okmulgee, in the county ofOkmulgee and State of Oklahoma, have inventednew and useful Improvementsin Window-Pulleys, of which the following is a specification.

This invention relates to pulleys and more' window-stile and isespecially constructed to prevent the sash cord and window-stile p frombinding during the action of the raising or lowering the windows, andfurther prevents the escape of the sash cord from said pulley, andfurther to so construct the inounting for the pulley to facilitate aready and quick adjustment of the same to the window-stile, and stillfurther to so form the mounting or shell whereby its accidentaldisplacement and rotation with respect to the window-stile is prevented.

With the above and other objects in view, the invention consists 'in thenovel features, details of Construction and combination of parts whichwill hereinafter be more fully set forth, illustrated in theaccompanying drawing and pointed out in the appended claims.

In the drawing:

Figure 1 is a front elevation of the pulley fitted to a window-stile;

Fig. 2 is a central longitudinal sectional View therethrough;

Fig. 3 is a transverse sectional view of the device; and

Fig. 4:7 is a perspective View of the improved pulley removed from thecasement.

Referring more specifically to the drawing, in which like referencecharacters refer to corresponding parts in the 'several views, 5 denotesa shell constructed from an integral piece of sheet metal and graduallydecreasng in diameter throughout' its longitudinal eXtent to form theshell of a tapering formation and providing the same with an enlargedopen' front end 6 and a contracted discharge end 7, the contracted rearend being depressed at right angles with respect to the front end, owingto the fact that the shell is of substantially elbow shape. Thecontracted or discharge end 7 is flared, as better shown in Fig. 2 ofthe drawing, to

p prevent the cutting of thesash cord andthe like during the raisngorlowering of the windows. The walls of -the shell forming the enlargedfront opening thereof are thickened at diametrically opposite points asat 8 'for 'thepurpose of reinforcing the shell. A grooved pulley 9occupies the space between the thiekene dportions S- of the casing andis rotatably mounted upon the spindle 10. The enlarged open end 6 of theshell is formed with an annular circular fiange ll which serves as astop when the shell is in applied position and limiting the insertion ofthe shell withinthe opening 12 of the stile 13. A pair of ribs 14 isformedintegral with the shell and is disposed longitudina'lly thereof onthe upper and bottom surface thereof and arranged at diametricallyopposte points, said ribs adapted to engage with the pair ofdiametrically opposed V-shaped recesses of the opening 12 wherebywhenthe shell is inserted in the window casement the engagernent of theribs with saidgrooves prevents any accidental 'rotation thereof.

Thesaid thickened portions s of the shell aside from serving as areinforcement there- V for also tends to accurately position the' grooveof the pulley in longitudinal alinement with the contracted rear end 7of the shell whereby preventing any binding action of the cord with theinner contour of the shell when it is desired to manipulate the windows.i The underneath surface of the shell at a point to one side of and inspaced parallelism with the lowermost rib is a slot 15 which permits ofthe insertion therethrough of a fastener l in the form of a nail or thelike whereby the shell will be prevented ,from any outward movement withrespect to the window casement and retain the same flush with the windowgrooves at all times and prevent the breakage thereof by the contact ofthe same with the windows during the hoisting or lowering action athereof.

From the foregoing description taken in connection with the accompanyingdrawing, the advantages of Construction and of the method of operationwill be readily apparent to those skilled in the art to which theinvention relates, and while I have described the principles ofoperation of the devce together with the deVice which I now consider tobe the best embodiment thereof, I desire to have it understood that thede- Vice shown is merely illustrative and that such advantages may hemade When desred as are within the scope of the'cltim appencled hereto.

I claim:

A sash 'cord pulley comprising :L shell tapering throughout itslongitudinal eXtent to provide the same with an enlarge'd front end anda contracted rear end, the contracted rear end of the shell beingdis-posed at right angles with respect to the enlarged front end thereofand fiared, an' annular flange forned on the enlarged front end of saidshell, rihs forme& on the outer eriphery of the shell and extendinglongtudinally thereof, the Walls of the shel forning Copies of thispatent may be obtaned for the enlarged front opening thereof beingprovided With thiekened portions serving as a reinforcenent therefor, agrooved puHey journalecl 'within the 'thickened Walls, the saidthickened p'ortions of the casing retaining the pulley in longitudinalalinement With the fiared oontracted rear end of the shell,substantially as and for the purpose specified.

, In testnony Whereof I &thx my signature in presence of two wtnesses.
